17. Withdraw your feet from the house of your neighbor, lest, when he has had his fill, he may hate you.
18. A man who speaks false testimony against his neighbor is like a dart and a sword and a sharp arrow.
19. Whoever sets his hopes on the unfaithful in a day of anguish is like a rotten tooth and weary foot,
20. and like one who loosens his garment in cold weather. Whoever sings verses to a wicked heart is like vinegar on baking soda. Just like a moth to a garment, and a worm to wood, so too does the sadness of a man do harm to the heart.
21. If your enemy is hungry, feed him. If he is thirsty, give him water to drink.
